MB102 Breadboard Power Supply Module 3.3V/5V
Description:
The 3.3V/5V output MB102 Breadboard power supply module is an easy-to-use, most useful breadboard component that can be added to any breadboard-related projects where 5V, 3.3V, or both power requirements are required. Its ease of use allows users to connect any DC power supply unit that has 6.5-12 VDC power output from a barrel jack. The board has two independent channels of power output for breadboards. These power channels can be independently configured for 3.3V, 0V, and 5V operations.

Features and Specifications:
- Input voltage: 6.5 – 12V
- Two Independent Channel
- Output voltage: 5V, 3.3V (adjustable via jumpers. 0V, 3.3V, and 5V configuration)
- Output current: Maximum output current 700mA
- Onboard berg male header for GND, 5V, 3.3V output
- ON-OFF Switch is available.
- USB (Type-A) input is available.
- DC Barrel Jack input is available.
- Onboard power LED
- Dimension: 53mm x 33mm (L x W)

MB102 Breadboard Power Supply Module 3.3V/5V Pin Configuration
Depending on the needs of our circuit, a Breadboard Power Supply Module accepts input through a barrel jack from a battery, a 12V adapter, or any other source and delivers a 5V or 3.3V tension to it. Soon, we’ll integrate Arduino into our circuits, and every Arduino circuit we create will function at those voltage levels. The pin configuration of the BBPS module in tabular is described as follows:
| Pin Name | Function |
|---|---|
| Left rail jumper (voltage selection) | 5 VoltsOFF (ground)3.3 Volts |
| Right rail jumper(voltage selection) | 5 VoltsOFF (ground)3.3 Volts |
| Output Headers | 2 output bergs of 3.3 Volts2 output bergs of 5 Volts4 output bergs of GND |
| DC Input jack | 6.5 Volts – 12 Volts Input port |
| USB Input jack | Input port |
